PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 608,202, dated August2, 1898. Application filed september 30, 1896. Qerial No. 607,384. (Nomodel.)

To all whom it may concern.-

Be it known that I, ASAPH M. KLECKNER, a citizen of the United States,residing at Findlay, in the county of Hancock and State of Ohio, haveinvented certain new and useful Improvements in Pipe-WVrenches; and I dodeclare the following to be a full, clear, and

exact description of the invention, such as will Figure 1 of thedrawings is a perspective;

View; Fig. 2, a detail View to show the wrench open, and Fig. 3 asimilar View showing the wrench closed.

In the drawings, A represents a wrench formed of four pivoted links CD EF and a lever B,'having the end cam 12. p The outer link F has a cavityon the back of its free end, in

l which works the cam 12, while the lever B is so fulcrurned near theouter end of link 0 that it may be turned slightly beyond a right man toanother without losing its grip upon the pipe. The link 0 has a cavity 0to receive the head of the other terminal link F, as shown in thedrawings.

I am aware that United States Patent No. 547,653, granted to Wiegand andBurr October S, 1895, shows and describes alink wrench which pulls uponthe hook end by the end of the handle as it slides about its fulcrum ina tangential direction on the links; but mine has not only this action,but an additional positive, radial, and clamping action due to thecain-shapedend of the lever, the cam-surface being so arranged as topermit the leverhandle to be turned beyond a right angle to the'pipe,thus making a lock which enables it to be transferred from one Workmanto another without loosening the grip upon the pipe. I

What I claim as neWis- A link wrench having the lever 13 f ulcruniednear the end of one terminal link and pro vided with an end cam whichworks in a cavity f of another end link, the lever being thus al-,
